Opinion for Vaccination Covid-19.

Dear Mam/Sir, My father had a long history of diabetes before 21 Dec 2020. He was diagnosed with Cholelithiasis with cholecystitis and hence Gall bladder removal surgery was performed. He had co-morbid conditions Viz. Diabetes, CKD, BP, Hypertension, Prostate issues and Liver Cirrhosis that were kept under check at the time of surgery. Post surgery, he was put on insulin and other medications for healing. Two months after, when his diabetic levels and other co-morbid factors got stabilised, his medicines were discontinued except for Prostate issues. He had developed some infection due to which his right feet got swollen up. To combat the issue he was on medications until 10 days back and now seem to have cured it. Kindly guide me, with his comorbidities under remission for now and his ongoing medications for prostate, will it be fine if we get him vaccinated against Covid-19? What medicines to take before & after taking the vaccine so that he pulls through between the two doses well.
